[解析]
(1)A.推理判断题。根据第一段中的Coached by his mother who was 81 at the time(由当时81岁的母亲指导)和第二段中的Cliff Young's training method was just running after his sheep(克里夫•杨的训练方法就是追赶他的羊群)可知,他没有专业的教练和专业的训练方法,由此可推知,他的训练很随意。故选A。
(2)B.词义猜测题。根据画线词后In fact,some tried to stop him from running the super﹣difficult race because they thought Cliff Young could die because of the heat and fatigue(疲劳).After all,he was 61 years old!Cliff Young当时已经61岁了,人们担心他可能会因为炎热和疲劳而死去,因此他要参加超级马拉松的决定似乎是"极其危险的"。A.Quite simple.非常简单的;B.Highly risky.极其危险的;C.Really surprising.非常令人惊讶的;D.Extremely reasonable.极其合理的。故选B。
(3)C.推理判断题。根据第四段中的While the young racers slept,he continued to race throughout the night(当年轻的赛车手睡觉时,他整晚都在继续比赛)和He even gave away his prize money to the rest of the runners after him(他甚至把自己的奖金给了后面的选手)可知,Cliff Young不仅有坚强的意志力,还很慷慨。故选C。
(4)B.主旨大意题。通读全文可知,本文主要讲述了具有运动精神的Cliff Young在61岁高龄时赢得超级马拉松比赛冠军的故事。B.A true story of an amazing sportsman.(一个了不起的运动员的真实故事。)符合文意,故选B。
